defmodule FNV do
  @moduledoc """
  Fowler–Noll–Vo hash functions collection.

  Please refer to the module of the variant you want to use for more details:

  - `FNV.FNV1`
  - `FNV.FNV1a`

  ## Difference between both variants

      The only difference between the FNV-1a hash and the FNV-1 hash is the
      order of the xor and multiply. The FNV-1a hash uses the same FNV_prime
      and offset_basis as the FNV-1 hash of the same n-bit size.

  It is recommended to prefer `FNV-1a`, as people state that this variant
  produces slightly better results than `FNV-1`.
